SASH-FASTENER.

To all whom it may concern.'

Be it known that we, WILLIAM C. MAT` man and TWILLIAM Kooi-n citizens ofthe United States, residing at Brooklyn, in the county of Queens andState of New York, have invented certain new and useful 11nprovements inSash-Fasteners, of which the following` is a spccication, referencebeing had to the accompanying drawings.

This invention relates to new and useful improvements in windowconstructions and particularly to sash holders.

The invention has for its primary object a simple, durable and eflicientconstruction of sash holding device which may be easily manipulated tohold the sashes in various adjusted positions.

Vlfith this and other objects in view, the invention consists in certainconstructions, arrangements and combinations of the parts that we shallhereinafter fully describe and claim.

For a full understanding of the invention, reference is to loe had tothe following description and accompanying drawing, in which,

Figure 1 is a vertical transverse sectional view thereof. Fig. 2 is anenlarged detail sectional view showing the holder, and Fig. 3 is afragmentary view of a part hereinafter specifically described. y

In describing our invention, we shall refer to the drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which- 1 indicates a wall of a structure havinga stationary window-frame 2 formed therein and movably mounted in thisframe is an auxiliary frame 7, the latter frame being preferably hingedto the stationary frame. The sill 4 of the frame 2 and the lower sill 8of the auxiliary frame 7 are offset coincident with one another toprovide abutting shoulders, whereby to limit the outward movement of theauxiliary frame in the stationary frame, as clearly shown in Fig. 1 ofthe drawing. Slidably mounted in the auxiliary or secondary frame 7, arethe upper and lower sashes 9 and 10, respectively, and our inventionprimarily contemplates the provision of means to retain these sashes intheir various adjusted positions in the auxiliary frame.

In the side rails or stiles of the secondary frame 7 are counter-sunkthe bars 11, the

front faces of which are substantially corrugated or otherwise similarlyserrated to provide the spaced concave recesses 12. Counter-sunk in theouter faces of each of the stiles of each sash is a metallic frame 13,which lhas an outer plate-like member 14 formed thereon. This plate-likemember 14 is provided with a slot 15 through which a locking bolt 16 isadapted to project, the outer end of this locking` loolt is convexlydesigned as shown at 17 and a rack 1S is formed on the upper edge ofthis bolt. A pair of parallel arms 19 'are formed on the bolt whichproject through openings in a wall of the frame and encircling thesearms between the last mentioned wall and the head of the bolt are thecoil springs 20, which normally force said bolt to its extendedposition. Rotatably mounted in said frame 13 is a pinion or the like 21,the teeth of which are disposed in mesh with the teeth of the rack 18,whereby when said bolt is moved in the frame, said pinion will berotated. y

Mounted in the upper portion of the frame 18 to move vertically therein,is a locking pawl or stud 22, the head of which is some what conical indesign and adapted for engagement with theteeth of the pinion 21. Ashank 23 extending upwardly from the head 22 is guided through anopening in a wall of the upper portion of the frame and encircling thisshank between the last mentioned wall and the head 22 of this pawl, is acoil spring 24, which normally forces said pawl downwardly intoengagement with the teeth of the pinion 21. From this construction. itwill be seen that the locking bolt 17 will be normally forced to itsextended position to rest in engagement with the wall of a cavity 12 andthe same will be retained in this position through the locking of thepinion 21, the springs 20 and 24 being of suilicient strength to overbalance the weight of the sash proper. When force is applied to thesash, however, the tension of these springs may loe overcome and thesash may be raised or lowered, the particular shape of the head of thebolt and the shape ofthe recesses permitting said bolt to readily rideover the spacing portions of the bar 11. It will be understood that asthe bolt is forced inwardly, the pinion 21 will be .caused to rotate. asthe force will overcome the tension of the spring 24 and when the sashhas been raised or lowered to the desired point, itis obvious that thesaine Will 'be automatically held in its adjusted position.

Extending horizontally of the auxiliary or secondary frame 7 and mountedin .the stiles thereof, is a fiat bracing bar 25 and the meeting railsof the sashes 9v and 10 are grooved or oifset lfrom opposite edgesthereof, to receive this bracing barL therein, as clearly shown in Fig.l of the drawing. rIlhis bar should form a bracing and strengtheningmeans forthe secondary or auxiliary frame, when the lattery is disposedbeyond the main vorfstationary frame. From the foregoing, it Will beseenthat We have provided a simple, inexpensive and etlicient meansfor'carry'ing out the objectsl of the invention and While We haveparticularly described the elements best adapted to perform'thefunctions set forth, it is obvious f thaty yvarious changes in form,proportion and in the minor details ofconstruction maybe resortedv toWithout departing from thel spirit; 'or sacricing any of the principles0f; `the invention.

Having thus described this invention, what We claim is t ln a Windowconstruction, the combination -With a franie, anda sliding sash suitablymounted therein; of a notched bar Counter- 30 sunk in a stile of saidframe, a frame counter-.sunk in a stile of said sash, a spring forcedlocking bolt carried in said frame and adapted to project therebeyondfor engageinent with said notched bar, the upper 35 edge of said boltbeing provided With teeth,` a pinion rotatably-mounted'in saidlast'mentioned frame and meshing With the teethon said bolt, :andaspring forced locking pawl mounted in said frame and normally en- 40gaged With the teeth of said pinion.'
